It's funny. Europeans tend to like the White or Red versions whereas the North Americans like the Silver and Black.
I think geography plays a big part in color selection.
Agree. On vehicles, North Americans mostly chose "non-colors" likes shades of white, grey, black, and very muted "colors", although they seem to tolerate medium red. Bright "real" colors are rarely chosen.
That's why Honda plays it safe with white, grey, black, and red. Fewer unsold leftover bikes.
